Notes

Abstract: The Robalo watershed on Navarino Island, Chile, is a pristine watershed located within the Cape Horn Biosphere Reserve. While both the native and invasive vertebrates of the region have been heavily researched, little is currently known about the freshwater invertebrates that populate the streams. Because the developmental stages of aquatic insects are directly affected by temperature, their life histories can be used as baseline data to assess future impacts of factors such as climate change. In order to add to this baseline for the region, this study describes the life histories of Blephariceridae (Diptera) and Baetidae (Ephemeroptera) specimens collected from the Robalo River. Blepharicerid larvae were sorted into instars by head capsule development, and Baetid nymphs were sorted into developmental classes by wing pad size. Analysis of developmental stages and daily temperature led to the approximation of degree days for both insects.
